i think that aluminum blocks should be aloud in pro stock as long as the weight is still 3000#'s and were limited to on carb what diff does it make?

If the car meets min weight, and it is a unlimited CI class it really bears no reason for a no alum block rule to be in place, IMO

There are alum blocks out there now capable of 900 ci plus, but have fun with feeding it with a single dominator.

I've had the same opinion for a few years now. minimum weights are a crock also

I think the issue that may arise is that one would assume if you can run an aluminum block in Pro Stock you could also run one in Outlaw Pro Stock where dual carbs & nitrous are permitted (thus, feeding that 900" monster would be possible).

Interesting !

The two factor that first come to mind are - Weight and Cost. While I do not know the exact numbers - it will take about 150 lbs. off the front end and about $4000 off your wallet. (But I will admit that I have though about alum. small blocks - as a lower cost alternative to a monster big block and to help them make the lower weight).

As for Minimum weights - I personally do not like them. As long as we spec. the chassis and tubing size (for safety reasons).

Just as a reminder - there are Pro-stock cars out there right now that are lighter then some of the Pro-mod rails. With the new rules for MRA Outlaw-pro stock - may become even lighter.

As for the Outlaw Pro-stock class having alum blocks - It would put it so close to the Pro-mod class - that you might as well combine the two (something that I see could happen - because there seems to be a decline in Pro-mod cars and the performance of the two are or will be very close). But that's just my opinion.

As for feeding a 800 or 900 c.i. with one 4 barrel - There are single carbs out there now that flow close to 2000 cfm. Even with a good modified 1250 I have to think that a good tuner could easily push over 1450 hp out of a 813 and with some of the "outlaw fuels" that are out there 1550 - 1600 could be obtainable.

ok so allow aluminum blocks in pro stock and outlaw pro stock then combind outlaw with pro mod more cars in outlaw or pro mod means more payback right all the pro stock guys with cuts spend 60-80$'entry''to run with pro mod cars anyways just ideas for 09

I have a hunch you will not see Alum blocks in Pro-stock for quite some time.

As for combining the two classes (outlaw-pro & pro-mod) - you already know I think it could happen - BUT - it is just my opinion.

If we were to limit the rails to one (1) NOS stage / system - I feel the competition would be very close. Power, tires and fuel are all pretty equal. Weight being the only factor that may need some thought.

Some might like to see it - some will disagree all together - But I still think it could make a very exciting class. If promoters & racers want to trim 11 classes down to 7 - well you have to start somewhere.

Yes - many run two stage. But I look at like this - you have 3 classes. Outlaw pro-stock, Pro-mod cuts and Pro-mod paddles. by limiting rails to 1 stage of nitrous and combining the 3 classes to make 2 (outlaw pro cuts & pro-mod paddles) The rails would drop down a class (so to speak) so both types of vehicles would still have two classes to run (if they like). This is just food for thought, But it may help make for a bigger class and a possible bigger payout. Promoters & track owner cannot continue to have more then 3 or 4 classes, Unless there is a larger vehicle count in them to help offset the costs. (sponsor support will come only when we can show them unity, stabilization and consistent turnout for shows) I also for see the combining of outlaw super-stock and pro-stock in a similar way (with cuts and paddles also). If we are going to keep weight rules in the classes a simple weight break would be all that is needed to install a balance between these two classes.

Besides It would not stop the rails (Pro-Mod) from bumping -up into class 5 & 6 and adding (using) the second stage.

Getting back on the topic of Alum blocks - If we allowed them for the outlaw pro-stock trucks (in the above scenario - It would give them an unfair advantage over the rails

well in the midwest here with my group we allow aluminum blocks,injection,nitrous,dual carbs and back halves/ cut tires and stretch in our prostock we have a class we call pro dot which is just like class 3 now- no nos, dot only,cast block single carb. very popular class around here- and yes most if not all of our prostock trucks can run with and do sometimes beat the pro mod rails. heres a few pics

I have seen some of those on the stompers site - looks and sounds like some pretty wild stuff out there. hopefully I will get to see some of them at Tex's race in Oct.

I never realized that they ran / allowed Alum blocks in your Pro-stock class. If I understand you correctly - is it a more popular class then the Pro DOT you mentioned? or did I get it backwards

Do you allow rails into the Pro-stock class?? (I think there is a possibility of some real hype for a race of this nature).

Once they figure out the weight issue - (or change the minimum weight for Pro-stock) - the rails will not stand a chance.

only ever had two guys run aluminum blocks- one is retired and sold to a guy tin tx and the other one went back to boat racing- both were also the onkly injected trucks in the class. the big thing in this class most of these guys run small blocks and heavy nitrous. we dont allow rails in the prostock class but most of the bump up to the pro mod class and run the nitorus and inj rails. and yes pro stock in my are is more popular than the pro dot- mainly because the equalizer is allowed- nitrous. but yeah im working on getting a big bunch of them to come down to tex's race oct 4th. come see them on the fastrack and then watch some of them tackle the bog. anyways i have some footage from brookfield from last year where a bunch of them all met up and some more from my area if anyone wants to swap videos or dvd's.

MRA or NMRO, it's all the same. I read the NMRO book when i started, It stated FACTORY BLOCK, then I went to the first event. Didn't know Merlin and Dart were factory's I thought they were talking about
Chevrolet & Ford. Boy did I waste a lot of money on a legal motor to run class 3. So smoebody should make up there mind and do it quickly.

Pro stock MRA reads
ENGINE
1) Any automotive type engine acceptable
2) Engine must be located with # 1 spark plug no more than 12” behind the center of the front axle tube
3) No aluminum engine blocks
4) Any type of cylinder head and intake manifold allowed
5) Maximum of 4 barrels of carburetion (split and stretched Dominators allowed, single Predator only)
6) Vacuum pumps and dry sump allowed
7) No nitrous allowed

Vehicles must meet all safety requirements.



Suggest when building for a particular class of rules ask questions prior to
spending $$$ you might just have a different view than that of the sanction body thet wrote the rules..
It never hurts to ask when in doubt and it might just help you make better deceisions during your build.
